(Closed) Hair growth tips

Does anyone have any inexpensive hair growth tips? I eat fairly healthily and it’s a balanced diet with lots of vitamins etc but I can never seem to grow my hair far beyond shoulder-length. I try to have it trimmed regularly(ish!) to get rid of the split ends. I’d be open to taking supplements or changing shampoo if there’s something anyone can recommend? Thanks!

I have started taking prenatal vitamins ( not prego, have no desire to be prego) My hair dresser told me to try it to grow my hair out for the wedding. I got a bottle at the drug store for about 5$ and I have seen a huge difference in my hair and my nails!
